Adscita statices
Mae’n arwynebol debyg i’r Coediwr Prin (A. globulariae) a’r coediwr Bach (A. geryon), ac mae angen gofalu gwahaniaethu rhyngddynt. Fe’i ceir yn aml yn ymborthi ar flodau megis Bara’r Cythraul, y Benlas Wen ac Ysgall y Gors.
Mae’n treulio’r gaeaf fel larfa. Ar y dechrau mae’n turio trwy’r dail, cyn ymborthi ar y tu allan i’r dail is. Mae’n chwileru mewn sidangod a wëir ganddo yn isel uwchben y ddaear, ynghudd ymhlith y llystyfiant.
Mae’r oedolion yn hedfan yn agos i’r ddaear, gan aros yn aml i gymryd neithdar o flodau megis Mieri ac Ysgall. Gellir gwahaniaethu rhyngddi a’r Fritheg Berlog ar sail y perlau gwynnaidd mwy niferus sydd ar du isaf yr adennydd cefn, y sieffrynau duon sydd o gwmpas y perlau allanol, a’r smotyn canolig du sy’n fwy o faint.
Erys y glöyn byw yma’n eang ei ddosbarthiad ac yn niferus mewn mannau yn yr Alban a Chymru, ond mae ei niferoedd wedi gostwng yn arw yn Lloegr.
Mae’n hawdd peidio â gweld ein glöyn byw brodorol lleiaf i gyd, yn rhannol oherwydd ei faint a’i liw tywyll, ond yn rhannol hefyd oherwydd na ddeuwn o hyd iddo’n aml ond ar glytiau bach o laswelltir cysgodol lle mae ei unig blanhigyn bwyd, sef Meillion Melyn (Bysedd Mair), i’w weld yn tyfu.
Until recently this was only a rare immigrant to mainland Britain, but it is now resident in small numbers in Devon. It also appears occasionally elsewhere on the south-west coast and is resident in the Channel Islands.

Caterpillar Food Plants
Caterpillars feed on the foliage of a range of trees, including birch (Betula) and oak (Quercus).
The name 'Wax Moth' refers to the moth's lifestyle - it lives in beehives, where the larvae feed on the honeycomb. Adults can be attracted to light.
The males of this species have a distinctively concave outer edge to the forewing; the females are generally plainer in appearance with a less concave edge.
Flight Season
